Materials Science Camp

posted July 2019

This was MEE’s 13th year as a sponsor of ASM International Materials Science Camp for high school students. ASM Materials Camp utilizes hands-on learning principles of applied math and science for a truly unique, team-based problem solving experience that explores materials science and engineering principles.

The students are assigned a failure analysis project on the first day of camp and spend a day in the laboratories at MEE examining their samples and gathering data.  They prepare their samples in the metallographic lab, view the microstructure using SEM and metallographic microscopes and perform Rockwell hardness tests all under the direction of  industry and education based Materials Mentors.

Three MEE staff, Larry Hanke, Kurt Schenk and Neal Hanke, were camp mentors for the entire week of camp.

This week, MEE hosted University of St Thomas Materials Science students in our laboratory. Students toured our metallography and light microscopy labs and were presented a brief introduction to scanning electron microscopy.

Staff engineer, Neal Hanke, arranged a display of some representative failure analysis projects to demonstrate the range of materials and failure modes we have investigated in our lab.

Corrosion and Failure Analysis

posted August 2018

The NACE International (National Association of Corrosion Engineers) Central Conference in Omaha is just wrapping up.  MEE staff engineers Ryan Haase and Neal Hanke have been taking turns attending technical presentations and talking to colleagues at the MEE booth in the exhibit hall.

This year’s conference location in Omaha, just a few hours drive from our Minneapolis location, was a good opportunity for us to discuss local corrosion issues and how MEE can assist in addressing these issues. One of the key benefits of partnering with MEE is our fundamental understanding of materials behavior, including mechanical and corrosion failure mechanisms.

MEE engineers, Ryan Haase and Neal Hanke, will be attending the NACE International (National Association of Corrosion Engineers) Central Conference in Omaha on August 6-8. The technical program will include presentations on failure analysis and MIC, Microbiological Influenced Corrosion.  The MEE staff specializes in root-cause failure analysis. Our experience encompasses many types of material behavior and modes of failure including mechanical and corrosion mechanisms.

MEE will have a booth in the exhibit hall. Look for the booth with the cool microscope images of corrosion and MIC.

Last Thursday we hosted thirty high school students at MEE  as part of a week-long Materials Science Camp sponsored by the MN Chapter of ASM International.  Under the direction of  industry and academic based “Materials Mentors”, students learned about the process of running a failure analysis investigation. MEE provided a space for the students to get hands on experience with sample preparation, Rockwell hardness testing, light microscopy and scanning electron microscopy.

 

 

Three of our staff, Larry Hanke, Kurt Schenk and Neal Hanke, were  camp mentors. This was MEE’s twelfth year sponsoring the camp.

Journal of Failure Analysis and Prevention

Alkaline Carbonate SCC Failures at a Refinery, co-written by MEE staff engineers, Ryan Haase and Larry Hanke was recently published in the Journal of Failure Analysis and Prevention ( First Online: January 16, 2018)

A metallurgical evaluation was performed to investigate two failures from carbonate-containing sour water service at a refinery. The paper details the visual, SEM/EDS, metallographic, and microhardness evaluations used to determine the failure mechanism for each refinery component.

 

 

 

 

 

Failure Analysis

“The greatest teacher, failure is.”

Wind Generator Blade Failure

This line from the latest Star Wars movie caught our ear. Any product failure can have serious consequences – from financial loss and/or personal safety perspectives. The expertise of the MEE engineering and technical staff encompasses a fundamental understanding of material behavior and a broad range of experience with different materials and types of failure. Paired with our technical expertise in failure analysis is an understanding that there is often an underlying root cause of failure that may be of greater importance to mitigating or preventing similar failures or improving a product’s future performance.

There is a lot to be learned from failure. MEE is your partner in the determination of the cause of a failure to minimize future risk.

Failure Analysis Presentation

posted February 2017

Larry Hanke and Dan Grice will be presenting at the  Minnesota Section of ASME (American Society of Mechanical Engineers) Spring Symposium on March 15 in Plymouth MN.

The title of this year’s symposium is “Failure, Test and Modeling Tools in Engineering Design”. Larry and Dan’s presentation will cover advice on field practices to prepare for failure analysis, laboratory test methods for evaluation of mechanical behavior and corrosion, failure analysis tasks useful for product improvement efforts, examples of the analysis of field failures and laboratory test specimens, and the application of test data to product development.

 

On the Road Again

Larry Hanke, will be speaking on Forensic Materials Engineering for Product Liability Litigation at the November meeting of  the Metro NY-NJ chapter of ASM International. The presentation will discuss potential materials related problems in product design and manufacturing that can lead to product failures. Failure mechanisms, including fracture and corrosion, as well as the material properties and service conditions that cause these failures will be covered. In addition, he will discuss special considerations for the process of investigating product failures involved in litigation from the materials engineering prospective.

MEE Senior Materials Engineer, Dan Grice, was just named to the Board of Directors for the Failure Analysis Society  (FAS) of ASM International.  Dan will be acting as liaison to the FAS Membership Committee. Among his goals will be to develop programs within FAS to increase membership and improve services for the emerging professionals demographic.

“The Failure Analysis Society is the newest affiliate society from ASM International. Founded in 2016, this society is dedicated to advancing the important role failure analysis plays in the materials science industry. We aim to promote more safe, reliable products by study of the many ways in which failures occur and to educate the larger engineering, manufacturing, and user communities regarding our findings.”
